Well I'm definitely in favour of mapping the boundary ways: hedges, fences, walls. I do not see any general value in mapping fields one by one, unless there are particular cultural reasons (for instance the Cheshire Cheese in Hope, Derbyshire, has maps showing all the historical field names on

Hedges are also rendered at higher zoom levels. Mapping hedges alongside roads had inspired me to try mapping roads as areas, not too sure if its been a success. Phil (trigpoint) -- Sent from my Nokia N9 On 30/04/2013 12:09 Henry Gomersall wrote: On Tue, 2013-04-30 at 11:15 +0100, Ed Loach

This is quite reasonable, although as I use farmland for all agriculture (but not viticulture or orchards) I had never appreciated that it seems to have become synonymous with arable. I still think landuse=farmland, farmland=arable is a better way of tagging ( a tad friendlier to data consumers).
